fix(extensions): address PR review on assess extension

Resolve review feedback on github/spec-kit#3568:

- catalog.json: bump top-level updated_at to this revision (2026-07-17)
- extension.yml + catalog.json: shorten the assess description to under
  the documented 200-char manifest limit (kept aligned across both)
- extension.yml: make the before_specify hook prompt condition-neutral
  (it fires on every /speckit.specify, so it must not claim "no
  assessment found")
- intake.md: fix slug normalization to explicitly allow lowercase
  letters a-z (the old rule permitted only digits and '-', contradicting
  the offline-mode example)
- intake.md + research.md: require a sanitized source URL (strip
  userinfo and credential/signature query params) instead of persisting
  a verbatim URL that could leak secrets into project artifacts
- decide.md: remove the "trivially small" exception so a go always
  requires a shaped concept, making verdict behavior deterministic and
  consistent with the guardrails and README

-- `ASSESS_DIR/concept.md` **SHOULD** exist. If missing, you may still decide, but a `go` verdict without a shaped concept must be downgraded to `needs-clarification` unless the idea is trivially small — a go should not hand `specify` an unshaped idea.

 - Read every artifact present (`intake.md`, `research.md`, `problem.md`, `concept.md`) — the decision must be consistent with all of them.
 - If `ASSESS_DIR/decision.md` already exists, ask whether to overwrite (interactive); in automated mode, refuse.

 Each idea gets its own directory under `.specify/assessments/<slug>/`. Resolve the slug in this order:
 
-1. **User-provided slug**: If the user explicitly passes a slug (e.g., `slug=offline-mode`, `--slug offline-mode`, or an obvious slug-like token), use it verbatim after normalization (lowercase, hyphen-separated, no spaces, no characters other than `-` and digits). Do not append timestamps or numbers.
+1. **User-provided slug**: If the user explicitly passes a slug (e.g., `slug=offline-mode`, `--slug offline-mode`, or an obvious slug-like token), use it verbatim after normalization (lowercase; hyphen-separated; no spaces; keep only lowercase letters `a–z`, digits `0–9`, and `-`). Do not append timestamps or numbers.
 2. **Interactive mode** (a human is driving): If no slug was provided, **ask the user** and wait. Suggest a 2–4 word kebab-case candidate derived from the idea as a default.
 3. **Automated / non-interactive mode** (no human to ask): Generate a concise slug yourself (2–4 kebab-case words). The generated slug **MUST** produce a unique directory — if `.specify/assessments/<slug>/` already exists, append the shortest disambiguating suffix (`-2`, `-3`, …) or a short ISO-style date (`-20260715`). Never overwrite an existing assessment directory.
